I'm truly sorry for disappointing you, mathmf.  I actually made a BI route, but I left it out because I wasn’t happy with how the animations turned out. I didn’t want to delay the whole update even further because of it.
However, as I previously mentioned to a few of my patrons on Subscribestar, I may choose to redo those scenes and provide a mini-update later. Or—and this is something I’ve been toying with since—maybe I save it for the next update and give your character, Rob, and Roby a full-on multi-route storyline. It could go either single or SiC, depending on your earlier choices and how many C-points you’ve stacked.
Let me know what you think, your feedback is always welcome!
